I am about to pull the trigger and get a MP40. I am getting tired of playing the aim game with 2 K4's. The problem with the K4's is im getting alot of sand bed movement, I think from them fighting each other. Will I have the same problem with the MP40? Also should 1 MP40 be enough for a 90g? I am hoping to only have to use the MP40.
I am probably ordering it this Monday
Thanks
